10 Claims

1. A radioactive chemical waste treatment apparatus comprising:

an adsorption unit comprising a radioactive chemical waste adsorption member for adsorbing and separating radioactive chemical wastes from a radioactive chemical waste-containing fluid; and

a regeneration unit which is in fluidic communication with the adsorption unit and is for regenerating the radioactive chemical waste adsorption member by desorbing the radioactive chemical wastes from the adsorption member with the radioactive chemical wastes adsorbed thereonto,

wherein the radioactive chemical wastes comprise radioactive iodine,

the radioactive iodine comprises at least one selected from the group consisting of I⁻, I₂and CH₃I,

wherein the radioactive chemical waste adsorption member comprises a support and an adsorbent, and

wherein the adsorbent comprises at least one selected from platinum (Pt), palladium (Pd), ruthenium (Ru), osmium (Os), rhodium (Rh), iridium (Ir), and an alloy thereof.
